+ Enable journaled, bitmapped or direct (passthrough) mode. Journaled mode is the default when this option is not specified.
+ It provides safety against crashes, but can be slow because all data has to be written twice.
+ Bitmap mode is more efficient since it requires only a single write, but it is less reliable because if data corruption happens when the machine crashes, it may not be detected.
+ Direct mode disables the journal and the bitmap. Corresponds to the "direct writes" mode documented in
the dm-integrity documentation.
Note that without a journal, if there is a crash, it is possible that the integrity tags and data will not match. If used, the journal-*
options below will have no effect if passed.
